This year, I am going to do the e-experiment with my P6s again after last year experience [Link]. I have included the data validation in the form after reading the responses from my colleagues’ who had done the experiment last Friday. On seeing their responses (like including mm in their answer and giving more than one response), I suddenly remembered that my little rascals also made the same mistakes last year. Guess it slipped my mind as I did not blog it down. I should have put in the data validation in the form in the very first place. It is an oversight on my part.
As the remaining three classes have not done the experiment yet, I quickly put in the data validation in the Google Form. To find out how to use the data validation, check out this link
Have tried the experiment 2nd time. For this year, I gave more detailed instructions due to the nature of the class. This included:
(1) What does the bubbles contain?
(2) What do we need to measure the number of bubbles?
(3) Giving them the distances and make sure that that they recorded on their activity book.
I then ended off the lesson by highlighting two ways to test for photosytnthesis : (1) Number of bubbles (2) Testing for starch
Some interesting observations:
(1) Some students does not know how to count “1 minute” . They think that 1 minute is up when the clock hand reaches 1.
(2) Students knew that the answers must be more or less the same. I heard some conversation that “your answer is not close to mine”. Good to teach them about reliability.
I think it is important for the kids to experience this simple experiment.At least, they are “doing” the experiment. Whenever I review photosynthesis with them, I can also say, “Do you remember the experiment we are doing in the computer lab? ” What is that all about”? By referring to this “doing”, hopefully, they can remember the facts about photosynthesis better!
This e-experiment serves a different purpose from my last year class. For my class last year, I want them to experience what a scientist do. Same experiment, different purpose.
